RAIL-CHAIR.

27, 1912. Serial No. 722,619.

all whom t may concern Be it known that I, PAUL HEBERT, a subject of the German Emperor, andresiding at Benrath, Germany, have invented a new and useful Improvement in Rail-Chairs; and I do hereby declare the following to be a full, clear, and exact description of the same.

This is a division of application, Serial Number 609763, filed February 20, 1911, which resulted in Patent 1,042,343, dated oct.. 22, i912.

The present invention relates to railway rail chairs for railway sleepers and more l level.

particularly to a novel construction for accurately, quickly and reliably clamping the rails to the chairs.

In the accompanying drawing, showing 'by way of example, embodiments of the invention: Figure 1 is a. longitudinal vertical sectional view of a sleeper, the chairs being shown in elevation; Fig. 2 is a similar view on a larger scale of a portion of the sleeper, and one chair; Fig. 3 is a plan of the chair; Figs. 4 and 5 are views similar to Figs. 2 and 3, but showing a modification, and Fig. (3 is a small fragmental view similar to Fig. 2, but showing another modification.

Of the various constructions herein illustrated, by way of example, Fig. 1 gives a general idea how the chairs are secured to the sleepers and the rails to the chairs. I-Ierein the chairs are shown embedded in a concrete sleeper, but it is, of course, possible to adapt the chair to be secured to any suitable sleeper of any suitable material.

Referring particularly to Figs. 1 and 2, a rail chair 10 is embedded in the'concrete sleeper 11, reinforced by a framework of rods 12 extending through the sleeper. The sleeper is further reinforced by a separate framework 13 situated at a lower As illustrated, the embedded part of the chair comprises a face plate 14, and downwardly flaring legs or walls 15 and 16, the inner wall 16 being provided with intermediate openings 17 through which the rods 12 pass. The ends of the rods 12 are bent over and secured to the lower edge of the outer wall 15 as shown. This arrangement forms an efficient anchorage for the chairs and reinforcement for the sleeper. The bearing plate 14 is adapted to receive the base 18 of the rail, and is provided at the inner edge with a claw-shaped lug 19 adaptrail base.

ed to engage over the railbase. At the outer edgeof the bearing plate, thev rail chair is provided lwith an undercut recess 20, forming a projecting edge Vto the bearing plate substantially coincident with the edge of the This recess slidably receives the U-shaped clamping member 21 adapted to receive the edges of the bearing plate and rail base between its diverging arms. This clamping member 21 may be tightly forced or wedged against said edges of the rail and plate, thus wedging said edges between the diverging arms at the same time. This forcing may be accomplished by means of the wedge 22 interposed between the clamping member 21 and an abutment 23 as illustratedA in Figs. 2 and 3, or it may be accomplished by screw bolts 24 having threaded engagement in lugs 25 and provided with jam nuts 26.

The modification shown in Fig. 6 is similar to the arrangement of Fig. 2 except that the clamping member 27 is provided with an overhanging lip 23 engaging over the oppositely disposed wedges 29 one of which engageswith the abutment 30.

I claim as my invention:

l. In a rail chair, the combination of a bearing plate provided with an undercut projecting edge extending from front edge to rear edge of the bearing plate; an abutment opposite said projecting edge; an elongated member of U-shaped cross-section extending from said front to said rear edge and having diverging parts embracing said projecting edge; and a forcing device between said abutment and member.

2. In a rail chair, the combination of a bearing plate provided with a bearing face and an undercut open ended recess extending from front edge to rear edge of the bearing plate and forming a projecting edge; an overhanging lug at the side of said face yopposite said projecting edge; an abutment at the side of said recess opposite said projecting edge; an elongated clamping member of U-shaped cross-section, extending from said front to said rear edge and having diverging parts adapted to extend over and under said projecting edge; and a forcing device engaging between said abutment and clamping member.

3. In a rail chair, the combination of a bearing plate provided with a lbearing face and an undercut open ended recess extending from front edge to rear edge of the bearing plate and forming a projecting edge, the recess having a floor lower than and parallel to the bearing surface; an overhanging lug on said plate and adapted to engage over the edge of a base of a rail having its opposite edge registering with said projecting edge; an abutment at the side of said recess opposite to said projecting edge and extending higher than said projecting edge; an elongated clamping member, of U-shaped cross-section, extending from said front to said rear edge and having diverging parts adapted to engage over and under said projecting edge and the adjacent edge of a rail; and a forcing device engaging between said abutment and said clamping member and pressing on the clamping member at points near said front and rear edges.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
